LASER SAFETY
The following information is provided to comply with the rules imposed by
international authorities and refers to the correct use of the DS2400 scanner.
Standard Regulations
This scanner utilizes a low-power laser diode. Although staring directly at the
laser beam momentarily causes no known biological damage, avoid staring
at the beam as one would with any very strong light source, such as the sun.
Avoid that the laser beam hits the eye of an observer, even through reflective
surfaces such as mirrors, etc.
This product conforms to the applicable requirements of both IEC 825-1 and
CDRH 21 CFR 1040 at the date of manufacture. The scanner is classified as
a Class 2 laser product according to IEC 825-1 regulations and as a Class II
laser product according to CDRH regulations.
There is a safety device which allows the laser to be switched on only if the
motor is rotating above the threshold for its correct scanning speed.
The laser beam can be switched off through a software command (see also
«Beam Shutter» in the WinHost Help On Line).
WARNING
Use of controls or adjustments or performance of
procedures other than those specified herein may
result in exposure to hazardous visible laser light.

1 GENERAL FEATURES
1.1 INTRODUCTION
The DS2400 laser scanner satisfies the most advanced needs of a wide
range of users. It has been developed focusing on the realistic requirements
of its target market. The outstanding result is an extremely compact, costeffective and easy to use industrial scanner.
The DS2400 belongs to the generation of Datalogic
scanners that operate under the 'C' programming
environment, which is a recognized industry standard.
A standard application program is factory-loaded onto
the DS2400. This program controls barcode reading,
serial port interfacing, data formatting and many other
operating and control parameters.
It is completely configurable from a host computer
through the WinHost utility program provided on
diskette with the scanner, or through ESC sequences
via the serial interface.
If the Standard Application Program doesn’t meet your
requirements, please contact your local Datalogic
distributor.
1.2 DESCRIPTION
Some of the main features of DS2400 are listed below:
• small dimensions and light weight.
• software programmable scanning speed (400 to 1000 scans/sec) on all
models.
•
linear and raster versions.
•
connector and junction box versions.
General Features - 1.1

The RTSAUX and CTSAUX signals control data transmission and
synchronize the connected devices. If the RTS/CTS handshaking protocol is
enabled, the DS2400 activates the RTSAUX output to indicate a message is
to be transmitted. The receiving unit activates the CTSAUX input to enable
the transmission.

The meaning of the two outputs OUT1 and OUT2 can be defined by the user.
Refer to the WinHost Help On Line.
By default, OUT1 is associated with the No Read event, which activates
when the code signalled by the external trigger is not decoded, and OUT2 is
associated with the Right event, which activates when the code is correctly
decoded.
These outputs are both level or pulse configurable.
2.5 POSITIONING
The DS2400 scanner is able to decode moving barcode labels at a variety of
angles, however significant angular distortion may degrade reading
performance.
When mounting the DS2400 take into consideration these three ideal label
position angles: Pitch 0°, Skew 10° to 30° and Tilt 0°.
Follow the suggestions for the best orientation:
Installation - 2.17
DS2400
DATALOGIC
The Pitch angle is represented by the
value P in Figure 2.24. Position the
reader in order to minimize the Pitch
angle.
DS2400
Figure 2.24 - Pitch Angle
The Skew angle is represented by the
value S in Figure 2.25. Position the
reader to assure at least 10° for the
Skew angle. This avoids the direct
reflection of the laser light emitted by the
DS2400.
For the raster version, this angle refers to
the most inclined or external raster line,
so that all other raster lines assure more
than 10° Skew.
DS2400
Figure 2.25 - Skew angle
The Tilt angle is represented by the
value T in Figure 2.26. Position the
reader in order to minimize the Tilt
angle.

2.6 TYPICAL LAYOUTS
The following typical layouts refer to system hardware configurations. Dotted
lines in the figures refer to optional hardware configurations within the
particular layout.
These layouts also require the correct setup of the software configuration
parameters. Complete software configuration procedures can be found in the
Guide To Rapid Configuration in the WinHost Help On Line.
2.6.1 Point-to-Point
In this layout the data is transmitted to the Host on the main serial interface.
Host Mode programming can be accomplished either through the main
interface or the auxiliary interface.
In Local Echo communication mode, data is transmitted on the RS232
auxiliary interface independently from the main interface selection.
When On-Line Operating mode is used, the scanner is activated by an
External Trigger (photoelectric sensor) when the object enters its reading
zone.

2.6.2 Pass Through
Pass through mode allows two or more devices to be connected to a single
external serial interface.
Each DS2400 transmits the messages received by the auxiliary interface
onto the main interface. All messages will be passed through this chain to the
host.
When On-Line Operating mode is used, the scanner is activated by an
External Trigger (photoelectric sensor) when the object enters its reading
zone.
The main and auxiliary ports are connected as shown in the figure below:

2.6.3 RS232 Master/Slave
The RS232 master/slave connection is used to collect data from several
scanners to build either an multi-point or a multi-sided reading system; there
can be one master and up to 9 slaves connected together.
The Slave scanners use RS232 only on the main and auxiliary serial
interfaces. Each slave DS2400 transmits the messages received by the
auxiliary interface onto the main interface. All messages will be passed
through this chain to the master.
The master scanner is connected to the Host on the main serial interface.
The possible main interface types for the Master scanner are RS232 or
RS485. (20 mA C.L. can also be used if the INT-22 accessory is installed).
Either On-Line or Serial On-Line Operating modes can be used in this layout.
When On-Line Operating mode is used, the external trigger signal is
unique to the system, however it is not necessary to bring the external
trigger signal to the Slave scanners.
The main and auxiliary ports are connected as shown in the figure below.

2.6.4 RS485 Master/Slave
The RS485 master/slave connection is used to collect data from several
scanners to build either a multi-point or a multi-sided reading system; there
can be one master and up to 5 slaves connected together.
The slave scanners are connected together using RS485 half-duplex on the
main serial interface. Every slave scanner must have a multidrop address in
the range 0-4.
The master scanner is also connected to the Host on the RS232 auxiliary
serial interface.
The External Trigger signal is unique to the system; there is a single reading
phase and a single message from the master scanner to the Host computer.
It is necessary to bring the External Trigger signal to all the scanners.
The main and auxiliary ports are connected as shown in the figure below.

in Local Echo communication mode to control any single
scanner (visualize collected data) or to configure it using the
WinHost utility or Host Mode Programming procedure.

3 READING FEATURES
The number of scans performed on the code by the DS2400 and therefore
the decoding capability is influenced by the following parameters:
•
•
•
•
number of scans per second
code motion speed
label dimensions
scan direction with respect to code motion
About 5 scans during the code passage should be allowed to ensure a
successful read.
3.1 STEP-LADDER MODE
If scanning is perpendicular to the code motion direction (Figure 3.1 - "stepladder" mode), the number of effective scans performed by the reader is
given by the following formula:
SN = [(LH/LS) * SS] – 2
Where: SN = number of effective scans
LH = label height (in mm)
LS = label movement speed
in (mm/s)
SS = number of scans per second
Figure 3.1 - "Step-Ladder" scanning mode
Technical Features - 3.1
DS2400
DATALOGIC
For example, the DS2400 (800 scans/sec.) for a 25 mm high code moving at
1250 mm/s performs:
[(25/1250) * 800] - 2 = 14 effective scans.
3.2 PICKET-FENCE MODE
If scanning is parallel to the code motion, (Figure 3.2 - "picket-fence" mode),
the number of effective scans is given by the following formula:
SN = [((FW-LW)/LS) * SS] -2
Where: SN

For example, for a 100 mm wide code moving in a point where the reading
field is 200 mm wide at a 2000 mm/s speed, the DS2400 (800 scans per
sec.), performs:
[((200-100)/2000) * 800] - 2 = 38 scans
